Serial killer Mark Nash, who’s serving a double life sentence for murdering two people in Co Roscommon, has today lost his appeal against his convictions for a double murder in Grangegorman, Dublin in 1997.
Nash, who grew up in England and has family connections in Mayo, was found guilty in 2015 of murdering Sylvia Sheils and Mary Callanan in Grangegorman between 6 and 7 March 1997, but he accused the trial judge of not giving him a fair trial.
His barrister claimed he didn't adequately deal with the possibility of cross-contamination in relation to a forensically examined jacket.
He also accused him of inviting the jury to speculate in relation to admissions made by another man, who has since died.
But the Court of Appeal rejected all his grounds this morning and dismissed his challenge.
Mark Nash is also serving a double life sentence for murdering Carl and Catherine Doyle at their home in Ballintubber, Co Roscommon in August 1997.
